Apparatus and Method for Providing Accessible Home Network Information in Remote Access Environment

1. An apparatus for providing accessible home network information regarding one or more home networks that can be accessed from a remote access (RA) environment, the apparatus comprising: a channel-creation module which creates a communication channel via which an RA client and an in-home RA server can communicate with each other; an information-management module which issues a request for capability information, a credential list and a profile list to each of the RA client and the in-home RA server; an information-generation module which generates channel-creation information for creating a communication channel between the RA client and the in-home RA server based on the capability information; and a transmission/reception hardware module for transmitting the request to each of the RA client and the in-home RA server and receiving the capability information from each of the RA client and the in-home RA server.

2. The apparatus of claim 1 , wherein the communication channel is an RA Transport Agent (RATA) channel.

3. The apparatus of claim 1 , wherein the channel-creation information comprises profile information and credential information.

4. The apparatus of claim 1 , wherein the apparatus is based on Universal Plug and Play (UPnP) RA Ver 1.0.

5. A method of providing accessible home network information regarding one or more home networks that can be accessed from an RA environment, the method comprising: creating a communication channel via which an RA client and an in-home RA server can communicate with each other; if the RA client is connected through the communication channel, allowing the RA client to search for accessible home network information and providing the identified accessible home network information to the RA client; transmitting a request for capability information, a credential list, and a profile list to each of the RA client and the in-home RA server of the selected home network; receiving the requested capability information, a credential list, and a profile list from each of the RA client and the in-home RA server of the selected home network; generating channel-creation information for creating a communication channel between the RA client and an in-home RA server of a home network selected by the RA client; and transmitting the generated information, based on the received capability information, to the RA client.

6. The method of claim 5 , wherein generating the channel-creation information comprises: selecting capability information that can be used by both the RA client and the in-home RA server of the selected home network by matching capability information of the RA client and capability information of the in-home RA server of the selected home network; generating profile information that can use the selected capability information; and generating credential information that can be used to create a communication channel between the RA client and the in-home RA server of the selected home network.

7. The method of claim 5 , wherein the communication channel is an RATA channel.

8. The method of claim 5 , wherein the method is based on Universal Plug and Play (UPnP) RA Ver 1.0.

9. A method of providing accessible home network information regarding one or more home networks that can be accessed from an RA environment, the method comprising: issuing a request for a list of accessible home networks to a public RA server; receiving a list of accessible home networks from the public RA server and selecting one of the home networks in the received accessible home network list; receiving a request for capability information, a credential list, and a profile list from the public RA server; transmitting the requested capability information, credential list, and profile list to the public RA server; receiving credential information and profile information regarding the selected home network from the public RA server; and creating a communication channel for communicating with an in-home RA server of the selected home network based on the credential information and the profile information.

10. The method of claim 9 , further comprising accessing the selected home network through the communication channel and using a service that is available in the selected home network.

11. The method of claim 9 , wherein the communication channel is an RATA channel.

12. The method of claim 9 , wherein the method is based on UPnP RA Ver 1.0.
